The Black Cat(1934). It was the first of eight movies (six of which were produced by Universal) to pair actors Béla Lugosi and Boris Karloff. Edgar G. Ulmer directed the film; Peter Ruric, wrote the screenplay. The classical music soundtrack, compiled by Heinz Eric Roemheld, is unusual for its time, because there is an almost continuous background score throughout the entire film.

Gaslight(1940). Directed by Thorold Dickinson, based on Patrick Hamilton's play Gas Light (1938) which stars Anton Walbrook, Diana Wynyard, and Frank Pettingell. This film, which adheres more closely to the original play than the 1944 MGM adaptation, was released in the United States under the title Angel Street to avoid confusion with the 1944 version, which stars Charles Boyer and Ingrid Bergman.
